AUTOMATIC BRAKE.

SPECIFICATION formingpart of Letters Patent No. 774,913, dated. November15, 1904.

Application filed June 2,1904. Serlal No. 210,867. (No model.)

Tg all whom it may concern.-

Be it known that I, MILLARD A. FILLMORE, a citizen of the United States,residing at Blaine, in the county of VVhatcom and State of WVashington,have invented a new and use-- shoes; second, to adapt the brake to beeasily thrown out of operation when it is desiredto back the wagonwithout operating the brakeshoes; third, to adapt it to be employed witha wagon having not only a pivoted tongue, but also a removable body.

lVith these objects in view the invention resides in the novelcombination and arrangement of parts and in the details of constructionhereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure1 is a vertical central section, the wagon-body being shown inelevation; and Fig. 2 is a plan view with the wagon-body removed.

Like reference characters indicate like parts in the different views.

The body 1 of the wagon to which the improved brake of this invention isapplied may be removable in any suitable and welt-known manner to adaptthe wagon to be used-for carrying rails or the like. Adjacent to theseat of the driver is a brake-lever 2, which is connected at its lowerend with ashaft 3, that extends transversely across the bottom of thewagon-body 1 and is mounted in suitable bearings. Depending from thecentral portion of the shaft 3 is an arm {1. The brake-lever 2, shaft 3,and depending arm 1 are rigid with each other, so that when thebrake-lever is rocked in one direction the depending arm is moved in theopposite direction.

Fastened upon the wagon-body 1 and surrounding the brake-lever 2 is anelongated guide-bracket 5, which has at its forward end a projection 6and at its rear end a projection 7. When the brake-lever has been rockedforward. it may be engaged with and held by the projection 6, and whenit has been rocked .to the opposite extreme of its movement it may beengaged with and held by the projection 7 fora purpose hereinafter to bedescribed. Additional projections may be provided between theprojections 6 and 7, if desired.

Loosely surrounding the lower portion of the depending arm 4 is a loopor traveler 8, fastened upon the rear end of the wagontongue 9. Thetongue 9, which is broadened or enlarged at its rear end 'in awell-known manner, is formed with longitudinal slots 10 1O 10, throughwhich extends a cross-rod 11, attached to the forward hound-frame 12 ofthe wagon. By means of the rod 11 and slots 10 the tongue 9 is not onlypivoted to the wagon hound-frame in such manner that it may rise up anddown upon uneven roads or fields and be dropped to the ground when theteam is unharnessed, but it also is capable of moving longitudinallywith respect to the wagon-frame. A bolt-hole 13 is formed in the tongue9 adjacent to the central slot 10. This bolt-hole 13 is adapted toreceive a suitable bolt for holding the cross-rod 11 in the rear end ofthe slot 10, and thus preventing rearward longitudinal movement of thetongue 9 when it isdesired to back the wagon witl out applying thebrakes, as will be apparent hereinafter. The bolt-hole 18, of course, isused for the purpose described only when the wagon-body, 1 has beenremoved, and it is consequently impossible to use the brake-lever 2 inthe manner presently to be described.

Fastened to the rear end of the tongue 9 is a cross-rod 14 to which areattached links 15 15, connected at their rear ends with levers 16 16,pivoted upon the forward hound-frame 12 of the wagon. The levers 16 16are pro- The cross-piece 21 at the rear end of the.

tongue 9 is cut away on its lower surface, as shown at 22 22, adjacentto each link 15 to permit the forward end of the tongue to be tiltedupward on uneven ground without causing the rear end thereof to bearupon and bend or break the links 15.

The method of operating the improved brake of this invention will beapparent from the foregoing description in connection with the drawings.\Vhen the wagon reaches a downgrade and the team begins to hold back,the tongue 9 is moved rearwardly and the brakes are applied through thelinks 15 and levers 16. If it be desired to lock the brakes inengagement with the wheels, the brake-lever 2 is thrown forward andengaged with the projection 6. This movement of the brake-lever causesthe depending arm at to move rear-- wardly and by means of the loop ortraveler 8 to hold the tongue 9 immovably in its rearward position, thuslocking the brake-shoes securely against the wheels. If it be desired toapply the brakes with increased force, the brake-lever 2 is forced stillfarther forward, thus causing the tongue 9 to move still farther in arearward direction and applying the brakes more tightly. If it bedesired to prevent the brakes from being applied in order to permit thewagon to be backed, the brake lever 2 is thrown into its backwardposition and locked against the projection'Y. This action causes thedepending arm a to be swung forward against the rear end of the tongue9, thus preventing said tongue from moving rearwardly to apply thebrakes.

The elongated form of the loop or traveler 8, which loosely surroundsthe lower end of the depending arm 1, permits said loop to swing to oneside or the other as the wagon is rounding a curve. l urthermore, whenit is desired to remove the body 1 to permit the wagon to be used forcarrying rails or the like the depending arm slips out of the traveler 8and permits this result to be accomplished.

\Vhen the wagon is used without the body and it is desired to preventthe brakes from being applied while backing, an ordinary bolt is slippedinto the bolthole 13 in the rear end of the tongue, as previouslymentioned. Such bolt by preventing the cross-rod 11 from movinglongitudinally in the slots 10 insures that the brakes will not beapplied.

The device of this invention is strong, simple, durable, and inexpensivein construction, as well as thoroughly practical and eflicient inoperation. In its novel combination and arrangement of parts and in itsdetails of construction it presents an improvement over prior devices ofa similar character.

Changes in the precise embodiment of invention illustrated and describedmay be made within the scope of the following claims without departingfrom the spirit of the invention or sacrificing any of its advantages.

Having thus described the invention, what I claim is 1. In awagon-brake, the combination with the forward hound-frame, ofatransverse rod, a longitudinally-movable tongue having slots for thepassage of such rod, a pivot-rod carried by the tongue, a brake-shaftpivoted to the hound-frame and carrying brake-shoes, intermediate leverspivoted to the houndframe, and link connections between the brake-shoes,the intermediate levers, and the pivot-rod.

A wagon having a removable body, a depending arm thereon, means foroperating the arm, a longitudinally-movable tongue, a loop on the tonguesurrounding the depending arm and braking means operated by the tongue.

3. A wagon havinga hound-frame, brakeoperating nieans, a longitudinally-movable tongue pivoted therein, and a link connected with said tongueand with the brake-operatingnieans, said tongue having a cut-awayportion to avoid the bending of the link when the tongue tilts upward.

In testimony that 1 claim the foregoing as my own 1 have hereto affixedmy signature in the presence of two witnesses.
